Ran the CSV through our deduper first. Address quality is the strongest column in the file. Bought it to handle bathroom remodeling contractor lead-gen for the United States region. No complaints from the field reps.
Used it for a market-sizing exercise. Dedup pass only flagged 1.2% — cleanest dataset I've worked with. Bought it for our bathroom remodeling contractor outreach in United States. Worth the price.
